I trust the radar - I just just don;t rely on it, NO HUB on HC ,so your yea theory goes out the window for me, If I wanna look for Noobs to the game I look in FFA core, or TDM first then head towards Blitz or Infected after school times or weekend daytime.
Rushers/Campers/Patrol are just a style which I expect in every CoD or FPS game.
Ying yang is the the perks vs killstreaks , I'm not addressing your wrong or I'm right vice versa , In my experience of getting branded as a rusher or a camper with the community I'm in, it's a small amount so more than likely I see the same names over ,an over,and never will I want to be labelled as either, otherwise my foes know my style.
